Footnotes
- E "Earnings" as discussed here refers to salaries paid to players under MLB contracts and does not include advertising or other sources of income. All values are listed in nominal dollars.
- P "Average annual value" is calculated as the total value of a contract (less bonuses) divided by the number of years. A $20 million/2 year contract would have an average annual value of $10 million, even if the player actually received $9 million one season and $11 million in the other. This also does not include contracts for less than a season prorated in value for a full season such as Roger Clemens' 2006 and 2007 contracts. All values are listed in nominal dollars.
- a Dave Winfield initially negotiated a 10-year deal in 1980 worth a projected $25 million ($2.5 million per year). However, Yankees' owner George Steinbrenner reportedly had not fully understood a cost of living adjustment provision in it and the 10-year contract was renegotiated a few months later. The final precise value is unclear, although it fell between $20 and $25 million in total value ($2–$2.5 million a year).
- b Hershiser and Frank Viola both won the 1988 Cy Young Award and Viola signed an identically-sized $7.9 million, 3-year contract two months after Hershiser.
- c Rickey Henderson signed a $12 million, 4-year contract with the Oakland Athletics on November 28, 1989, 6 days after Puckett signed his $9 million, 3-year contract.
- d Roger Clemens signed a contract extension during the 2000 season covering 2001 and 2002 along with a player option for 2003. Clemens was paid $10.3 million each year for 2001 and 2002, with the same $10.3 million available if he elected to play in 2003 under his option. However, Clemens also received $10.3 million if he rejected the option. As a result he could effectively collect the full $30.9 million of contract value for only two years of play ($15.45 million annually). However, the Yankees valued this deal as a $10.3 million annually, three-year deal. He became a free agent after the 2002 season and ultimately resigned with the Yankees for a new, one-year contract in which they bought out the previous option.
